PATENT OFFICE 1 CHARLES J. THOMAN AND WILLIAM WESTCOTT, OF JACKSON,MICHIGAN, ASSIGNORS TO HINCKLEY-MYERS COMPANY, OF JACKSON, MICHIGAN, ACORPORATION OF MICHIGAN GrLASS CHANNEL REMOVER Application filed March-16, 1931. Serial No. 522,928.

This invention relates to the removal of window sash channels from theglass pane upon which the channels are mounted and has particularreference to mechanism such as a tool adapted to be employed to removemetal channels or the like from glass panes. It is particularly intendedfor use in removing metal window sash such as is used on the glass panesof closed automobile bodies in the doors windows, or Windshields of suchbodies.

An object of the invention is to facilitate the removal above specifiedby the provision of a tool which is simple in construction,

rapid in operation, and automatically adapted to adjust itself to thework in hand.

Various other meritorious features reside in the particular combinationand arrangement of parts to be hereinafter more clearly described inconjunction with the accompanying drawings wherein:

Fig. 1 is an elevation for our improved tool, partly broken away and insection.

Fig. 2 is an elevation at right angles to that of Fig. 1, partly brokenaway and in section,

of the operating end of the tool,

Fig. 3 illustrates one position in the operation of removal,

Fig. 4 is a plan view showing one means of holding the glass during theremoval of the channel.

Fig. 5 is a section through the glass clamping vise, and

Fig. 6 is a section on 66 of Fig. 4.

This tool comprises a lever 10 which includes means for clutching themetal channel 12 in which glass pane 14 is customarily mounted. It is sodesigned that upon application of power in a horizontal direction thechannel is loosened and withdrawn from the glass 14.

The lever 10 is provided with a movable member 16 pivotally disposedbetween the bifurcated rigid ends 18 and 20 of the lever. The member 16includes a pair of fingers 22 and 24 which are pivotally connected to adraw bar 26 which extends through the bore of the lever 10. This pivotalconnection is by means of the pin 28 which seats in the longitudinalguide slots 30 and 32 provided in the bifurcated lever arms 18 and 20.One purpose of these guide slots is to limit the axial movement of thedrawbar 26- as it is adjusted for various glass and channel combinationsby means of the knob 34 which threads over the externally threaded upperend 36 of the draw bar 26, and which bears against the end of the handle10 and constitutes an extension thereof.

A coil spring 38 is seated between a shoulder 40 in the axial bore ofthe lever 10 and a shouldered portion 42 at the extremity of the drawbar26 formed by the pivoted ends of the fingers 22 and 24. This spring proVides for the returnof the finger to normal position after the-channelhas been removed, or when it becomes necessary to move the leverlongitudinally to a point where the channel is still firmly secured tothe glass, and it maintains a normal spring tension on the fingers. Thespring also serves to permit axial adjustment of the drawbar 26 byrotation of the knob 34without unscrewing the knob from the threadedextremity 36 of the-said drawbar.

The bifurcated arms 18 and 20 of the lever handle are rounded at theirtips into the cam Shape illustrated at 44, the extremity of the cammingsurface being adapted to overlie the extremity of the fingers at anypoint of their axial adjustment. Flat springs 48 and 50 normallymaintain the fingers 22 and 24 in axial alinement as illustrated in Fig.1, and are secured to the sides of the lever. 10 as by means of screws52-.

Although it will be apparent that a. munber of structures for holdingthe glass and channelwhich is to be removed therefrom may be devised, wehave illustrated in Figs. 4-6 an improved visewell adapted to serve thisfunction. This vise may be made of two laterally extending members 54and 56 of suflicient length to overlap any glass which may be workedupon. Each of these members may be rubber faced, or cushioned, as bymeans of the strips 58 and 60 on the side which is adapted to contactthe glass. Means for drawing the members together are provided. This mayconsist of bolts 62 in conjunction with wing nuts 64 the said boltsbeing firmly secured in one of the members 56 and having a sliding fitin the other, 54.

Each of the lateral members is cut away as at 66 and 68 on adjacentsides sufiiciently to allow clearance for the end sash channels of theglass, if it is considered that it is the side sash channel which isbeing engaged by the tool, and to insure pressure being exerted entirelyacross the surface of the glass on clamping movement to avoid possiblebreakage thereof.

In the operation of the tool to remove a sash channel the bifurcated endof the handle. is inserted, as shown in Fig. 4 over the sash channelwith the fingers 22 and 24 engaging the channel grippingly on oppositesides of the glass, and the rounded tips of the bifurcated end bearingagainst the vise members 54 and 56. The longitudinal edges of themembers 54 and 56 constitute fulcrum surfaces 46 upon which the cammingsurfaces 44 of the two arms 18 and 20 of the bifurcated end are adaptedto seat. The fingers 22 and 24 grip the metal channel 12, as clearlyindicated in Fig. 6, and reciprocal horizontal swinging movement of thelever 10 as shown in Fig. 4 will result in the graduated application ofdrawing power to pull the channel away from the glass positionedtherein.

Having I illustrated a preferred form of our invention, variousmodifications will be portion being pivotally articulated and saidgripping means being adjustable lengthwise with respect to said thrustportion.

4. A pulling device for removing a frame from a panel comprisingabutment means adapted to be detachably secured to opposite sides of thepanel adjacent said frame to extend along said frame, a pulling toolhaving gripping fingers adapted to engage said frame and provided withthrust portions extending beyond said gripping fingers on both sides ofthe pane and rockably engaging said abutmentupon both sides of thepanel, said gripping fingers pivotally articulated with the thrustportions to permit rockable movement of the thrust portions over theabutment without any corresponding rockable movement of the fingers withrespect to the frame.

In testimony whereof, we, CHARLES J. TI-IOMAN and lVILLIAM lVns'roo'rr,sign this specification.
